The month ahead - August

Winter 2018/19 weather 

Tonight wet weather continues to affect northern and western Britain but the rain becomes patchier. In the rest of the country it stays dry with variable amounts of cloud.

Tomorrow morning showery rain in the north peters out and most of the country has a dry day with warm sunny periods. Temperatures in East Anglia and the London area could reach 30C (86F). During the afternoon thicker cloud brings outbreaks of rain back into Northern Ireland.

Fine and hot in the south

On Friday an Atlantic flow continues to bring the risk of cloud and showery rain to the north. In southern and probably central areas it should be fine and hot. Temperatures could reach a scorching 34C (93F) in the south east.

The weekend is set to bring a lot of fine weather but there could be a few showers around. The south will be quite hot and warmer conditions filter northwards with temperatures in much of Scotland climbing above 21C (70F).

Hot start but mixed next week

High pressure probably remains close to the UK next Monday and Tuesday so there should be a lot of fine weather. During the middle of the week there are signs of it becoming cooler and more mixed for a time as areas of low pressure approach. The extent of any change is uncertain and there are signs of high pressure building back quite quickly from the southwest.
